4.7L (PowerTech V8) - Limited
Petrol
Check this by turning the steering wheel lock-to-lock while stationary; listen for any groaning or whine, as the hydraulic power steering systems in these XK models can occasionally show signs of age-related seal fatigue.
While driving at a steady speed on a flat road, gently touch the brakes; if you feel a shudder through the pedal, the heavy nature of the Commander means the front rotors may have warped or reached the end of their service life.
Test this by ensuring every power window and the sunroof operate smoothly; the wiring looms within the door jambs are known to become brittle over time, which can lead to intermittent electrical gremlins.
During the test drive, monitor the coolant temperature gauge carefully; ensure it sits steady in the middle, as these 4.7L engines prefer a cooling system that has been flushed and maintained regularly to avoid heat soak.
Usually the window where suspension bushings and ball joints may show natural wear, often resulting in a slightly loose feeling in the steering.
The typical point where the alternator and water pump should be inspected for bearing play, as these are common service items at this stage of the vehicle's life.
A milestone where the transmission fluid service history becomes critical to verify, ensuring the smooth shifting of the 5-speed automatic remains consistent.
Regularly verify the engine oil level between services, as the PowerTech V8 likes to stay well-lubricated to keep the timing components happy.
Keep the transmission and differential fluids fresh to help protect the heavy-duty driveline components during everyday driving.
Perform a quick visual check of the engine cooling hoses to ensure they remain supple and free of cracking.
Lubricate the door hinges and latches occasionally to prevent the common squeaks associated with a vehicle of this stature.
Monitor the battery health periodically, as these electronics-heavy vehicles require a strong, stable voltage to keep all the onboard modules functioning correctly.
Estimated repair costs if issues arise
Given the Commander's weight, the shocks and control arm bushings often soften up. If this component needs attention in the future, it helps improve ride comfort and handling stability significantly.
To protect the V8 engine, replacing the radiator and hoses is a wise preventive measure if the service history is missing. Depending on the car's history, you might eventually need to budget for this to ensure reliability.
A ticking sound from the engine bay upon cold start is a common trait of these V8s. If you decide to address this, the estimated cost in NZ covers the labor-intensive process of replacing the gaskets.
